The Schedule referred to in theseA Letten Patent and :.rialclxxgy part of th@ m6- To all whom it amr/y concern:

Be it known that I, OTIs DEAN, of Richmond, in the county of Henrico, andState of Virginia, have invented a new and useful Improvement -in Vises and Drills; and I do hereby declare that the followin gis a full, clear, and exact description thereof, which will enable those skilled in the art to make' and use the same, refl 'erence being' had to the accompanyingl drawings, forming part of this specification.

This inventionrelates to improvements in the construction of the vise and drill recently patented to me, in which improved device the fixed jaw is made/use of as the stock of the drill-spindle, the movable jaw as the table and support'of the articles to be drilled, and the vise-screw as the feed-screw.

The present invention comprises an `improved arrangement of the vertical adjusting-spindle of the snpport for the jaw, aud the adaptation of the feeding or vise-screw, for operation either by the ordinary vise- Vlever or by the crank used for turning the drill-spinarrange it for working vertically in the- 'socket of the bracketG, and I turnIannular-grooves D in the said shank, at' suitable distances, into which the point of the set-'screw E may be forced to hold the vise at the required height, no matter what may be the direction of the support A.

' I propose to Vextend the vise-screw G beyond `the fixed jaw H sucientlyto form a shank, I, for the re-' ception of the crank K used for turning the drill-spindie L.

The continuous motion required for rotating the drills, makes it necessary that the jaw supporting the drill-spindle stand fronting the operator when drilling.

It is also neoessary,'for obvious reasons, that the drill-spindle be fixed in the permanenty jaw, and when used as a vise, this jaw should stand the same way, and the lever for turning the feed-screw when used for drilling must be at the opposite end, or behind the movable jaw; consequently only one such lever is employed, itmust be onthe wrong end of thescrew when used as a vise, and it would be objectionable to have one in each end.' Moreover, it would be diiicult to use one in the endv H, as it would interfere with the pro-f' jecting shank of the drill-spindle. Hence'the impor- 'tance of the arrangement of the crank used for turning the drill-spindle, to operate thev screw lwhen used as a vis nular grooves M, for holding them against end move'- ment in the fixed jaw by the set-screws N O. Having thus described my invention,

What I 'claim as new, and desire to secure by Lettrs Patent, is

1. Forming a hole for the handle inthe but ends of the screw, and extending said ends beyond the jaws, so as to apply the lever to eitherend, substantially as described. f

2. The combination, with the vise-jaws, ofthe socketed bracket G, -grooved shank A, and set-screw E, as and for the purpose set forth.

The'above specification vof my invention signed by me, this 15th day of July, 1869. OTIS DEAN.
